What is a contagious disease?
contagious disease is a disease you can catch from another person. Often, when you are approaching a person, contact with a person or touching something that touches, it is enough for you to get this disease. These diseases do not necessarily have to be dangerous or threatening life, even if some may be. For example, colds are not usually dangerous, but the HIV virus that causes AIDS is.
Many times contagious diseases spread by transmission of body fluids such as saliva or blood. Some pathogens that can cause you to cause you in the caps of saliva. The act of coughing and sneezing causes these droplets to fly through the air and possibly infect someone else. Even sneezing or cough in hand can be a vehicle for dissemination of the disease, as pathogens can be transferred to an object when it is touched by an infected person. You can even carry pathogens by shaking your hands with a person after you cough or sneezing.
Some countries have virtually eliminated a number of fatal contagious diseases using vaccines. A vaccine solution composed of a weak or dead version of the pathogen that causes contagious disease. In some cases, the vaccine may also be part of the pathogen. The vaccine is introduced into the body by a healthy person, many times by injections. The aim is that the body identifies these diseases and creates antibodies to combat pathogen.
The final goal of this method is that an inoculated individual becomes immune to the subsequent exposure of a contagious disease. Although many versions of vaccines include injection, some such as influenza vaccine can also be administered by using a nasal spray. Whether you get a vaccine once or the other method depends on age and other factors. Either the vaccination process can have side effects associated with it, so it is important to find out what to expect. Some examples of a contagious disease whose spread has been controlled by the use of a vaccine are chickenpox, rubelledKy, mumps and measles.
Although it may not be possible to completely eliminate pathogens that cause contagious diseases, there are some steps that can be taken to limit changes in contractual contracts. Hand washing can often eliminate bacteria on your hands. When you sneeze or cough, be sure to do so inside the fraudster of your arm. This will prevent bacteria from getting into their hands and preventing them from becoming air. It is also important to reduce the exposure of body fluids, which means without sharing needles, regardless of sexual intercourse or touching body fluids or items contaminated with body fluids without proper protection.
